Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a component feeder suitable for use in a chip component mounting apparatus that automatically mounts chip components onto an electronic circuit board.

Background technology and its problems As the demand for smaller and thinner electronic devices increases, the configuration of electronic circuits shifts from the conventional configuration of electronic components with lead wires to high-density packaging circuits using chip components. Chip component mounting devices are now being used as devices that automatically mount chip components onto electronic circuit boards. In such an apparatus, chip parts are supplied one by one from a magazine of a parts supply machine to a chucking head, and the chucking head grasps and mounts the supplied parts one by one.

In general, a chip parts feeder has a part that has the function of storing various types of chip parts in a certain capacity, and a part that has the function of arranging the stored chip parts, separating them one by one, and feeding them in a predetermined direction. , and parts that have the function of selecting a predetermined type from among various chip parts. The above functions are mainly dependent on the magazine, which is generally detachably attached to the parts supply machine.

However, due to a change in the board mounted by the chip component mounting device, (a) there is a change in the sorting sequence for each type of chip components to be supplied, and (b) it becomes necessary to supply a new type of chip component. When this occurs, a so-called setup change occurs in which the magazines are rearranged. This setup change work is essential for the efficient operation of the chip component mounting device, but if there are many types of chip components (about 50 types are planned) to be loaded on the component feeder, The more there are, the more time it takes,
Since the operating rate of the equipment deteriorates due to this loss time, economic efficiency is significantly impaired in the case of high-mix, low-volume production.

Purpose of the Invention The present invention has been made in view of the above-mentioned circumstances, and its purpose is to provide parts that can significantly shorten the set-up time when changing types, and without losing the parts alignment function of the magazine. The purpose is to provide a feeding machine.

SUMMARY OF THE INVENTION In order to achieve the above objects, the present invention includes a sorting rotating section that is driven and rotated by a drive motor to sort parts, and a sorting rotating section that is detachably attached to the sorting rotating section and integrated with the sorting rotating section. a parts supply section that rotates, and a large number of magazines that are each removably attached to the parts supply section so as to be arranged in an annular shape as a whole in the parts supply section,
The component supply section has a fixed side part that is removably fixed to the sorting rotation part, and a movable side part that is connected to the fixed side part so as to be movable up and down with respect to the fixed side part, The magazine includes a magazine hopper fixed to the movable part;
a parts supply pipe that is connected to the magazine hopper so as to be movable up and down with respect to the magazine hopper and fixed to the fixed side part, and the movable part is moved up and down with respect to the fixed side part. The structure is further provided with a vertical drive mechanism that drives the vehicle.

With the above configuration, when changing the product type, the entire parts supply section including the magazine can be replaced with a spare parts supply section that has been set up in advance, which greatly reduces setup change time. Moreover, it is possible to provide a component feeder which has a simple structure and has an extremely good component alignment function of the magazine.

Embodiment Hereinafter, an embodiment in which the present invention is applied to a chip component mounting apparatus having two sets of chucking heads in the mounting head will be described with reference to the drawings.

(Schematic explanation of the entire chip component mounting device) In FIGS. 1 to 3, reference numeral 1 denotes a chip component mounting head, which has two sets of chucking heads 2 and 3 at mutually orthogonal positions. 4,
5, and is attached to a rotation shaft 6 which is rotated 90 degrees left and right alternately. According to the rotation of this rotation shaft 6, two sets of tracking heads 2,

In addition, each of the rotary parts feeders 7a and 7b includes
A plurality of magazines 10a, 10b, etc., which are classified according to the size and shape of chip parts, are attached, and the required magazines are moved to predetermined parts supply positions according to the above program. The chip parts in the magazine are then delivered to rotary parts feeders 7a and 7b.
Component delivery devices 11a and 11 provided in each of
The parts are fed out one by one from the parts supply ports 12a and 12b to the chuck portions of the chuck heads 2 and 3 by means of the part b.

Alternate rotation of the mounting head 1 every 90 degrees, feeding of the parts by the parts delivery devices 11a and 11b,
A series of operations such as moving the chucking heads 2 and 3 in the vertical direction and pressing the gripped parts onto the board 9 are performed by the cams 1 and 1 driven by the motor 13 via the reducer 14 shown in FIG. 15a, cam 2, 15b
The drive members 16a, 16b, etc. are operated in a correct order by the drive members 16a, 16b, etc. Opening/closing of switches that operate in connection with these sequential operations and confirmation of operations related to the program are performed using cam switches 19a, 19b, etc. provided on a cam switch shaft 18 driven via a cam shaft 17. It is done by folding.

(Schematic description of the chip component mounting head) Next, the chip component mounting head 1 is attached to the rotation shaft 6 (FIG. 3) which alternately rotates 90 degrees left and right, as shown in FIGS. 4 and 5. The holding member 25 is made up of a cross-shaped holding member 25, and the two sets of chucking heads 2 and 3 are attached to the holding member 25 in mutually perpendicular positions. The intersection point O of the orthogonal central axes 26 and 27 of these two sets of tracking heads 2 and 3 coincides with the axis of the rotation shaft 6. Each of the chuck heads 2 and 3 includes a chuck portion 43 that can grip a chip component and slide within the holding member 25, and a chuck portion 43 that can slide within this chuck portion 43 and holds the component gripped by the chuck portion 43 on the board 9.
It is composed of a push part 44 that pushes out upward.

The distal end of the chuck portion 43 has L facing each other.
Letter-shaped fixed side chuck 47 and rotating side chuck 48
The rotary side chuck 48 is configured to be rotatable around a fulcrum pin 51. A tension spring 52 is connected between these chucks 47 and 48.
A wide pawl 53 is provided at the tip of the stationary chuck 47, and a narrow pawl 54 is provided at the tip of the rotating chuck 48. The rotating chuck 48 on the opposite side of the claw 54 with the fulcrum pin 51 in between is extended in an L-shape in a direction parallel to the fulcrum pin 51, and a pressed portion 56 for opening and closing the chuck is formed in this extended portion. ing. Furthermore, the push part 44
A push rod 66 is provided between the chucks 47 and 48 at the tip thereof, and is slidable between the chucks 47 and 48.

The chuck portions 43 and push portions 44 of the chucking heads 2 and 3 are perpendicular to each other, but are configured to slide within the holding member 25 without interfering with each other. Further, reference numeral 105 shown in FIG. 4 is a sensor attached to the holding member 25 and activated by the pressed portion 56 of the chuck 48 on the rotating side. The sensor 105 confirms the chuck state from when the component is turned on until it is gripped and mounted on the board 9.

Next, as shown in FIGS. 1 and 5, when the chuck head 2 is rotated to the component supply position, that is, to the horizontal position, the pressed portion 5 of the rotary side chuck 48 is rotated.
6 is configured to come into contact with a pressing member 101a provided on the stationary side separately from the mounting head 1, thereby causing the rotating side chuck 48 to move against the tension spring 52 as indicated by the dashed line. Open as shown. When the parts are supplied between the claws 53 and 54 and the chuck head 2 starts rotating in the direction of arrow a, the rotating chuck 48 is released from the pressure of the pressing member 101a. 48 is closed by a tension spring 52, and the tip part is closed by the claw 5.
It was checked between 3.54 and 3.54. Then, the tracking head 2 rotates 90 degrees and stops at the mounting position while being checked (Fig. 6). Here, the first and second pressing levers 102 and 103 shown in FIG. 3 rotate in conjunction with the cam 15, and this rotation causes the push rods 102a and 103a at the tips to move downward at approximately the same speed. the round nut 63 on the head of the chuck part 43 of the chuck part 2 and the cap 73 on the head part of the push part 44 of the chuck head 2 are pressed downward. (Although not shown, the push rod 103a is 1
02a, and the push rod 102a is configured to be pressed via a compression spring. ) Therefore, the chuck part 43 and the push part 44 are moved downward together with the chucked chip part 104 against the compression springs 61 and 79, and the chuck part 43 is in a position where it may or may not come into contact with the board 9. Stop. However, since the push rod 44 can move forward independently, it continues to move forward and the push rod 66 at the tip of the push rod 66 pushes the tip part 1.
04 onto the substrate 9. However, at this time, the chuck part 43 starts to move backward, so the chip part 1
04 is detached from the claws 53 and 54 and attached to the board 9. When this attachment is completed, the pusher portion 44 also begins to move backward, and both the chuck portion 43 and the pusher portion 44 return to the backward movement position.

Then, the tracking head 2 rotates in the direction of arrow b again to receive the parts, but this time, the tracking head 2 that was receiving the parts during the above-mentioned mounting operation of the tracking head 2 3 comes to the mounting position, and the chip parts are mounted in the same manner as above. Then, by alternately rotating the mounting head 1 90 degrees left and right, the tracking head 2
and 3 alternately repeat the operation of receiving parts and the operation of mounting the supplied parts.

Note that the chuck 4 on the rotating side of the chucking head 3
8 is opened by the pressing member 101b.
This is done in the same way as in a.

(Description of Parts Supply Machine) The rotary parts supply machine 7 (7a, 7b are collectively referred to as 7) will be explained with reference to FIGS. 2, 7, and 8.

The parts feeder 7 has a fixed part 110 that is the center of rotation.

26, a ring-shaped lower annular member 135 fixed to the outer edge of the lower disc member 127, and an annular gear 128 fixed to the lower annular member 135. It consists of This gear 128 is meshed with the reduction gear 112, and the lower disc member 12
A vertical positioning pin 129 is located at a predetermined position of 7.
and screw holes 130 are provided, respectively. The outer edge of the lower disc member 127 is formed into a ring-shaped stepped outer edge 131 that extends one step lower, and the magazines 10 (10a, 1
An escapement (feeding member) 132 is located at the mounting pitch of the magazine 10, which receives chip parts one by one from the chips (collectively referred to as 10), feeds them out in the radial direction, and delivers them to the tracking head 2 or 3. (See explanation of parts delivery device). The escapement 132 stopped at a predetermined position (parts supply position)
is configured to be pushed out by a rotating lever 134 that is rotated around a fulcrum shaft 133 provided on the base plate 115.

The upper part supply section 114 has flanges 13 on the upper and lower sides.
an outer central member 138 having a diameter of 6,137 and fitted around the outer periphery of the inner central member 125; Plate member 1
It consists of 39. A ring-shaped stepped outer edge portion 140 of the upper disc member 139 is provided with a lock member for attaching a magazine, which will be described later, at a position corresponding to the escapement 132. At a predetermined position of this upper disc member 139, a position corresponding to the positioning pin 129 and the female screw hole 130 is provided.
A fitting hole 141 and a rod insertion hole 142 are provided, respectively. On the other hand, three vertical guide shafts 143 are fixed around the circumference of the upper flange 136 of the outer central member 138, and a cylindrical guide member 144 is slidably inserted into the outer periphery of the vertical guide shafts 143.
A horizontal plate 146 is attached to the upper flange 145 of. Between the horizontal plate 146 and the outer central member 138, three return tension springs 147 are stretched around the circumference, and the tension springs 14
The normal horizontal plate 146 is biased by the roller 1
22 have been contacted. Further, a holding plate 148 is fixed to the upper part of the vertical guide shaft 143 to connect these parts, and a handle 149 that can be raised and lifted is attached to this holding plate 148.

On the other hand, a connecting rod 152 is provided at a position corresponding to the female threaded hole 130 and the insertion hole 142, and has a handle 150 at the upper part and a male thread 151 formed at the lower part to be screwed into the female threaded hole 130. ing. That is, this connecting rod 152 is connected to the holding plate 1.
48 and upper flange 136 of inner central member 138
A cylindrical spring receiver 155 with a single flange is inserted into the lower step from below, and a compression spring 156 is further mounted on the outer periphery of the cylindrical spring receiver 155. is inserted. Therefore, when the connecting rod 152 is screwed into the female threaded hole 130 from the insertion hole 142, the cylindrical spring receiver 155 descends and its lower end surface contacts the washer 157 on the upper surface of the upper disk member 139. The connecting rod 152 is no longer screwed in and stops. That is, the cylindrical spring receiver 155 serves as the bolt head of the bolt, and since it is tightened via the compression spring 156, the screw 151 will not loosen. Further, on the outer edge of the horizontal plate 146, a magazine holder 158 made of iron is arranged vertically downward at a predetermined magazine pitch along the circumference.

With the above structure, when the threaded portion 151 of the connecting rod 152 and the female threaded portion 130 are uncoupled, the upper part supply section 114 and the lower sorting rotation section 113 are disengaged. Therefore, by raising the handle 149 and lifting it upward, the eighth
As shown in the figure, the upper part supply section 114 can be easily removed from the lower sorting rotation section 113.
In addition, to connect the two, align the fitting hole 141 with the positioning pin 129, and insert the inner surface 1 of the outer central member 138.
59 to the outer surface 160 of the inner central member 125 and push down the upper component supply section 114 to place it on the lower sorting rotation section 113. Then, by turning the connecting rod 152 to connect the two, the two are connected in the vertical direction.

Note that the fitting hole 141 is long in the radial direction and formed into a long hole that fits perfectly in the rotational direction, so it is easy to connect during the above connection, and there is no deviation in the rotational direction after connection, so that the upper part 114 is connected to the lower part 113. It is positioned accurately in the rotational direction, and rotational torque is transmitted from the lower part 113 to the upper part 114. Furthermore, as mentioned above, the upper part 114 and the lower part 113 are connected to the inner surface 159 of the outer central member 138 and the inner central member 125.
Since this is done by fitting with the outer surface 160 of the outer surface 160, the two do not shift in the radial direction due to this fitting. That is, the upper part 114 is precisely positioned and coupled to the lower part 113. On the other hand, the lower sorting rotating section 113 has a gear 1 necessary for positioning the rotating section.
28 and an origin described later are attached, and these remain as they are when the upper part 114 is attached or detached, so that the positioning of the rotating part will not be disturbed due to the above-mentioned attachment or detachment.

Next, as described above, the lower sorting rotation section 113 is rotationally driven by the motor 111 together with the upper supply section. ,
An origin detection sensor 161 provided on the fixed side is used. In other words, the sensor 161 detects the origin on the rotation side that should serve as a reference, counts the rotation of the motor 111 from this origin, and when this count matches a programmed value, the motor 111 is stopped. has been done. Further, by rotating the rotating lever 120 in conjunction with the cam 15, the sliding shaft 118 moves up and down,
As a result, the horizontal plate 146 and the magazine holder 1
58 moves up and down, the hopper case portion 166 of the magazine 10 moves up and down with respect to the component supply pipe 167. Although the details will be described later, the escapement 132 is pushed out by the rotation of the rotation lever 134 which is also linked to the cam 15.

(Description of Hopper Type Magazine) The hopper type magazine 10 will be described with reference to FIGS. 9 and 10.

The magazine 10 is molded from synthetic resin or the like, and includes an upper hopper case 166, a guide shaft 168 that guides the hopper case 166 in a vertically slidable manner, and a magazine lower member 169 attached to the lower end of the guide shaft 168.

That is, the shutter 177 is connected to the magazine lower member 169.
It is an L-shaped lever that is installed inside the lower member 169 so as to be rotatable around a fulcrum pin 178 fixed to the lower member 169, and is normally biased by a compression spring 179 so that one end 180 of the lever is attached to the part. Exit 175 is closed. However, when the magazine 10 is attached to the component feeder 7 and the other end 181 of the shutter 177 is placed on the component feeder 7, the shutter 177 rotates counterclockwise against the compression spring 179. , component outlet 175 is opened.

A stopper 182 consisting of a pin screwed into the guide shaft 168 is fixed to the guide shaft 168, and the forward protrusion of this pin 182 engages with a long hole 166a formed in the front surface of the hopper case 166. Possibly the guide shaft 16
8 is prevented from slipping out.

Next, the mounting and locking of the magazine 10 on the component feeder 7 will be explained.

At the bottom of the vertical magazine holder 158 provided in the component feeder 7, there is a horizontal guide groove 184 with a groove width corresponding to the thickness of the hopper case 166 of the magazine 10, and a cutout groove 185 for the component feed pipe 167. A horizontal holder 186 is provided.

On the other hand, the lower disc member 127 of the parts supply machine 7
A lower protrusion 18 of the magazine lower member 169 is attached to the outer edge 131 of the magazine 10 at each mounting pitch of the magazine 10.
A cutout 188 into which the side surface of the lower annular member 135 is fitted is formed, and the escapement 132 is disposed and configured to slide on the upper surface of the lower annular member 135 that is visible through the cutout 188. A ring-shaped edging member 189 (not shown) is attached to the front surface of this notch 188, that is, to the outer circumferential surface of the outer edge portion 131, in which a portion where the escapement 132 enters and exits is notched (not shown).

Further, the outer edge 140 of the upper disc member 139 has a recessed portion in the center, and guide surfaces 190 that are inclined in the magazine direction (forward) are formed on the protruding side plates. A lock member 192 with a notch 191 formed on the lower surface of each end.
is attached by a guide bolt 193.
The locking member 192 is guided through the elongated hole 194, and the stepped circumferential surface 19 of the upper disc member 139 is
A compression spring 196 tensioned between the magazine and the magazine 5 urges it forward, that is, toward the magazine side. The locking member 192 has a distal end portion formed at a protruding edge 19 formed on the outer periphery of the stepped outer edge portion 140.
It is normally stopped by contacting 9,
Also, the release lever 19 is attached to this lock member 192.
7 is installed.

To attach the magazine 10 to the parts supply machine 7,
With the guide shaft 168 fully raised and shortened, the hopper case 166 is first inserted into the guide groove 184 of the lower holder 186 of the magazine holder 158. In this way, the rubber magnet 173 on the back side will be attracted to the iron magazine holder 158, and the hopper case 166 will be attached to the magazine holder 158.
It is fixed at 8. Next, the lower part 169 of the magazine

78 reaches the lower end of the inclined guide surface 190, the locking member 192 moves back and the fulcrum pin 178 enters the notch 191 at the lower end and is locked. At the same time, the end portion 181 of the shutter 177
Since it is placed on the upper surface 198 of the stepped outer edge portion 131 of No. 27, the shutter 177 rotates and the component outlet 175 is opened as described above.

That is, in this state, the lower member 168 is locked vertically by the lock of the fulcrum pin 178, circumferentially by the fitting between both sides of the notch 188 and the lower projection 187, and radially by the lock. Member 192
The front surface 187a of the lower protrusion 187 is pressed against the ring-shaped border member 189 under pressure, thereby being accurately positioned and fixed to the component feeder 7. Therefore, since the guide shaft 168 attached thereto is also fixed, when the magazine holder 158 moves up and down, the hopper case part 166 is guided by the fixed guide shaft 168 and moves up and down. In this way, hopper 1
Since the parts supply pipe 167 moves up and down inside the hopper 17, by continuing this operation, the hopper 17
Parts inside the pipe 167 are facilitated to enter the pipe 167.

Next, to remove the magazine 10, press the compression spring 196
When the release lever 197 is pushed against this, the lock member 192 is moved back and the fulcrum pin 178 is unlocked, so the lower member 169 is pulled upward in this state. Then, by pulling the hopper case 166 forward, the magazine 10 can be removed from the component supply machine 7 very easily, together with the guide shaft 168, the component supply pipe 167, and the like.
Since the stopper 182 is provided, the hopper case 166 will not accidentally slip out from the guide shaft 168 in this removed state.

Note that the lower member 169 of the magazine 10 is connected to the outer edge 140 of the upper disc member via the lock member 192.
Furthermore, since the hopper case 166 is attached to the magazine holder 158, the parts supply machine 7
When the upper component supply section 114 is attached and detached in , the magazine 10 is attached and detached together with the upper component supply section 114.

(Description of Parts Delivery Device) Next, the chip parts delivery device will be described with reference to FIG. 9 and FIGS. 11A to 12B.

In order to receive the chip parts supplied one by one from the component supply pipe 167 of the magazine 10 and to send the received parts between the chuck claws of the chucking head 2 (the same applies to 3), the escapement (feeding member) is used. ) 132 and a pivot lever 134 are used. Escapement 13
2 is provided at each mounting position of the magazine 10 on the rotating side of the component feeder 7, and the rotating lever 134 is provided only at the component feeding position on the fixed side.

The escapement 132 is formed into a long rectangular parallelepiped, and the component receiving portion 233 at the tip thereof is formed into a flat plate with a thickness approximately equal to the height of the chip component (the height of the component coming down from the component supply pipe 167 of the magazine). has been done. It is provided in a guide groove 235 in the stepped outer edge portion 131 of the lower disc member 127 of the component feeder 7 so as to be slidable while being guided by the guide groove 235 and the upper surface 234 of the lower annular member 135. ing. and internal recess 236

For example, there is a square chip (rectangular chip) 2 at the tip of the
In the case of No. 39, as shown in FIG.
That is, a rectangular through hole 240 is formed with a shape and size suitable for inserting the descended component as it is. A rectangular notch hole 242 passing approximately through the center of the through hole 240 and having an opening 241 at the end is formed to intersect with the through hole 240 in the sliding direction of the escapement 132.

On the other hand, the chuck pawl 53 at the tip of the chuck portion of the chuck head 2 is formed wide enough to accommodate the component receiving portion 233 at the tip of the escapement 132, and the chuck pawl 54 is formed in the notch hole. 242 is formed to be narrow enough to pass through.

Since it is configured as above, magazine 1
The component 239 supplied from 0 is inserted into the through hole 240 at the tip of the escapement 132 stopped at a predetermined receiving position, and while being held in the through hole 240, the component 239 is inserted into the upper surface 234 of the lower annular member 135.
placed on top. However, since this through-hole 240 is formed to have almost the same shape and dimensions as the chip component 239 to be inserted, the inserted chip component will not fall or become misaligned within this through-hole 240. . Therefore, from this state, the escapement 132 is pushed by the rotating lever 134.
Even when the tip part 239 is moved onto the chuck pawl 53, the chip part 239 remains in a stable state held within the through hole 240, and is moved onto the wide chuck pawl 53 in this state.

In this state, that is, when the component 239 is placed on the wide chuck claw 53, the escapement 132
When the chuck head 2 is rotated in the direction of the arrow a while being held in the through hole 240, the chuck pawl 54 on the rotation side is closed by the biasing force of the tension spring as described above, and the component 239 is released. Both chuck claws 53,
Checked within 54 hours. At the same time, the narrow chuck claw 54 passes through the notch hole 242 and moves in the direction of arrow a while holding and chucking the head of the component 239. Therefore, part 239 is escapement 13
Since the parts are chucked while being held in the through-hole 240 of No. 2 and then moved to the mounting position after passing through the through-hole 240, there is no possibility that the parts may fall over or become misaligned during chucking, resulting in a chucking failure. Never.

Note that when the chuck pawl 53 passes through the notch hole 242, the rotary lever 134 returns, and the escapement 132 is returned to the predetermined component receiving position by the spring 238. When it returns, the chip part 239 descends from the magazine again and enters the through hole 2.
Since it is inserted within 40, escapement 13
2 is pushed by the rotating lever 134 and moves forward again, and the chuck claw 5 of the tracking head 2 returns.
The operation of sending out the parts is repeated between 3 and 54.

What is shown in FIGS. 12A and 12B is a case where the component is a cylindrical chip 243, and in this case, a circular through hole 244 that fits the cylindrical chip 243 is formed. And chuck claw 54
As in the case of the square chip, the notch hole 242 through which the through hole 244 passes has an opening 241 at its end, with its center passing approximately through the center of the through hole 244, and
44, and the width of this rectangle is smaller than the diameter of the through hole 244. Therefore, it is clear that the same effects as in the case of the square chip can be achieved in this case as well.

Effects of the Invention As explained above, according to the present invention, the parts supply section is detachably attached to the sorting rotation section,
Moreover, since a large number of magazines are removably attached to the parts supply section so as to be arranged in an annular shape as a whole, it is possible to change the parts such as changing the type of electronic circuit board on which the parts are mounted. When changing the product type, the entire component supply section including the magazine can be replaced with a spare component supply section that has been changed in advance. Therefore, the setup changeover time is significantly shortened compared to the conventional one, eliminating lost time, thereby significantly improving the operating rate of the device and increasing productivity, which is extremely advantageous.

Further, the magazine hopper is fixed to the movable side part of the component supply section, and the component supply pipe connected to the magazine hopper so as to be movable up and down is fixed to the fixed side part of the component supply section. The vertical drive mechanism drives the vertical movable side part up and down with respect to the fixed side part, so that the vertical magazine hopper moves up and down with respect to the component supply pipe. Therefore, even though the parts supply section is removable from the sorting rotating section, the magazine's parts alignment function, which promotes the entry of parts into the parts supply pipe, is extremely good.

Further, the hoppers of a plurality of magazines are respectively fixed to the movable side portion of the component supply section which is driven up and down by the up and down drive mechanism. Therefore, since a plurality of magazine hoppers can be simultaneously moved up and down by a common vertical drive mechanism, the structure for imparting a component alignment function to the magazine is extremely simple.
